Title: Improvements in mechanical fuses for shells
IPC: F42C9/14
Filed: 1923-11-29
Abstract: 214,924. Soc. J. Cockerill, and Ternstrom, E. Nov. 29, 1923. Projectile fuzes. - Clockwork time fuzes. A detent adapted to be released by the clockwork has a central opening for the primer carrier and covers the percussion cap until released; this detent and the firing pin are locked by a pin on a tube which sets back on discharge, unlocking these parts and a percussion fuze simultaneously; and the detent may be released by a spiral groove in a disc rotated by the clockwork, enabling this action to be spread over more than one revolution. In the combined time and percussion fuze shown in Figs. 3 and 4, the clockwork is contained in a case 41 held by elastic packing 21 in a hollow dome 18, and its escapement spindle is connected to a disc 25 having a rim 26, which confines a transverse detent 7 arranged with its spring 8 in a groove in the fuze body 1. This detent has a central opening embracing the end of the primer carrier 13 and a projection 30, which normally locks the spring hammer 5. A side piece of the detent at the same time covers the percussion cap 33. The spring hammer 5 is arranged in a transverse groove in the fuze body, and, together with the detent 7 and the disc 25, is locked by a longitudinal pin 29 carried by a tube 14, which, on discharge, deforms a winged sleeve 15 and sets back on a momentum striker 16 of the percussion fuze, thereby arming the percussion fuze and releasing the clockwork fuze at the same time. The clockwork is provided with a further safety catch, not shown, which is released by centrifugal force. Further, on discharge, a ring 22 sets back and locks the dome 18 to the fuze body 1. At the appointed time, if the momentum striker 16 has not acted on previous impact, a tooth 27 on the detent 7, under the combined action of centrifugal force and its spring 8, escapes through a notch in the rim of the disc 25, releases the spring hammer 5, and simultaneously brings a window 32 in front of the percussion cap 33 to allow access of the spring hammer thereto. In a modification, Fig. 9, the detent 7 has a pivoted tooth 37 which rides in a spiral groove 35 in the rim of the disc 25, and finally escapes by a notch 36. Another pivoted tooth 38 riding in the same spiral groove is carried by a lever 39 connected to an index 40, which is thus made to rise gradually to follow a spiral scale on the dome 18. This arrangement enables the adjustment of the time fuze to be spread over more than one revolution. A key 42a for setting the fuze is shown in Fig. 13.

Title: Improvements in or relating to gas plating
IPC: C23C16/448
Filed: 1954-10-20
Abstract: 787,076. Coating with metals. COMMONWEALTH ENGINEERING CO. OF OHIO. Oct. 20, 1954, No. 30148/54. Class 82(2) An object is coated with metal by heating a thermally decomposable metal-bearing compound to a temperature sufficient to produce vapours of the compound but insufficient to cause its decomposition, separately heating a carrier gas to a temperature above that required to vaporize the compound but below the decomposition temperature of the compound, flowing the heated carrier gas into contact with the heated compound to produce a mixture thereof, and heating the mixture to a temperature below the decomposition temperature of the compound immediately prior to introducing the mixture into a coating zone which contains the object at a temperature high enough to cause decomposition of the metal-bearing compound. Compounds which may be employed are molybdenum carbonyl, tungsten carbonyl, cobalt carbonyl, nickel carbonyl, iron pentacarbonyl, antimony hydride, tin hydride, chromyl chloride, copper nitroxyl and cobalt nitroxyl carbonyl. The carrier gas may be carbon dioxide, nitrogen, helium or argon. As shown in Fig. 1, carbon dioxide from a source 10 is passed into a carburettor 4 containing chromium carbonyl maintained at a constant temperature by a thermostatically controlled oil bath 2, the carbon dioxide being preheated to the same temperature by circulation through the coil 7. The carbon dioxide charged with chromium carbonyl vapour passes through heating jacket 11 and thence into heated chamber 24 the interior of which is thus coated with chromium. In two modifications (i) the carburetter 4 is not enclosed by the coil 7 but is separated from it by a short length of connecting pipe which is also immersed in the oil (Fig; 3, not shown), and (ii) the gas mixture emanat-i ing from heating jacket 11 is passed; through a second coil maintained in a con-  stant temperature oil bath, the gas mixture issuing from this coil passing through  a second heating jacket before entering the < coating chamber (Fig. 4, not shown). Methods of packing the carburettor are described in which (a) layers of chromium - carbonyl are supported on metal screens which may be separated by layers of glass wool (Figs. 2 and 6, not shown), and (b) glass beads are interspersed with fragments of chromium carbonyl - (Fig. 5, not shown). When the metal-bearing compound is liquid, a carburettor is employed having perforated horizontal screens spaced along its vertical axis.

Title: Process for the production of white clouded enamel and glazes
IPC: C10L1/10
Filed: 1933-10-31
Abstract: 409,597. Enamels and glazes. KREIDL, I., 5, Sebastian Kohlgasse, Vienna. Oct. 31, 1933, No. 30223. Convention date, Nov. 28, 1932. [Class 56.] Relates to the production of white enamels and glazes in which gas-clouding agents are used in conjunction with enamel frits which are colloidal in the slip, as described in Specifications 375,670, 375,672, 375,673, and 375,674. Such frits are liable to become dimmed during firing, and the present invention consists in overcoming this drawback by adding to the slip substances which bring about a partial conversion of those salts in the slip which favour the water-combining power of the clay. Suitable substances for the purpose are hydrochloric acid or compounds which yield hydrochloric acid, preferably chlorides of volatile bases, such as ammonium chloride. Examples of suitable mixtures are given in the Specification.

Filed: 1947-11-17
Abstract: 639,806. Fluid-pressure servomotor-control systems. LUCAS, Ltd., J. Nov. 17, 1947, No. 30427. [Class 135] Apparatus for controlling the supply of liquid fuel to a combustion chamber such as the combustion chamber of an internal-combustion turbine or a furnace comprises a fuel duct e, k, r containing a restricted orifice s of predetermined fixed area, a throttle i on the inlet side of the orifice connected to a piston or diaphragm d responsive to the pressure on one side of the throttle i, a second piston or diaphragm n responsive to the pressure between the throttle and the orifice, and a control valve z actuated by a spring-loaded lever v operatively connected through a thrust-piece x to the diaphragm n so as to be opened by the fuel pressure between the throttle and the orifice and also acted on by a capsule 4 subject to atmospheric or blown air pressure, the valve z controlling a fluid-pressure servomotor 3 regulating the fuel supply. The fuel duct e is formed as a byepass from a pipe g connecting the fuel pump to the burner h in the combustion chamber. The throttle i is shaped so that the pressure in the duct k bears a predetermined relation to the pressure in the passage e. The diaphragm d is loaded by a spring and subject also to the pressure on the outlet side of the orifice s through a passage o opening into a compartment p having an outlet q to a sump or to the pump inlet. The compartment p is divided from a compartment t by a diaphragm u which supports the lever v. The compartment t contains an evacuated elastic capsule 4 open to the atmosphere or to the blown air pressure, through a connection 5. The servomotor comprises a spring-loaded piston 6, the opposite sides of which are connected through a restricted orifice 10. Motive fluid from the pump is supplied through a passage 8 and escapes through a passage 2 controlled by the valve z. The piston 6 may control the output of the fuel pump or a throttle valve or byepass in the fuel supply line to the burner.

Title: Arrangement for reinserting the d.c. component into a signal with periodically recurrent reference values
IPC: H04N5/18
Filed: 1964-08-04
Abstract: 1,033,796. Television. FERNSEH G.m.b.H. Aug. 4, 1964 [Aug. 1, 1963], No. 30441/64. Heading H4F. The invention relates to a gated clamp circuit having a time constant which is short in the first part of the clamping time and continuously increases in the subsequent second part of the clamping time, which is utilized for reinserting the D.C. component into a signal with periodically recurrent reference values having interferences, e.g. noise, superimposed thereon, e.g. a television signal. As shown, capacitor 3 is connected to the load resistance 2 of tube 1 by way of which the signal is applied, and to the control electrode of tube 4, at which the reference value of the signal is to be brought to a fixed potential, e.g. earth, by means of clamp circuit 5 comprising four diodes. Before the clamping pulses are applied by way of capacitors 55 and 56 to the clamp circuit 5 they are partially differentiated in pulse shaper 6, which changes the rectangular clamping pulses with even tops applied by way of capacitor 62 to tube 61 and differentiating element 66, 67 into pulses having slanting tops of inverse polarity. Fig. 5 shows the manner in which the diode resistance R D  may from a very small value in the first part of the clamping time t1 be continuously increased in the second part t2 by a clamping pulse of specific shape such that its amplitude has an extreme value in the first part tl, which is at least so long that the diode is completely conductive, and that in the second part t2 this value is gradually reduced until the diode is blocked at the end of the clamping time. Thus in the second part t2 the interference superimposed upon the reference values is progressively integrated so that the clamping at the end of the clamping time is effected on about the mean value of the interference, whereas, in known clamp circuits which had short time constants the instantaneous value of the interference voltage would correspond to the reference potential at the end of the clamping time, and since this instantaneous value would be different for successive clamping times the brightness of individual or groups of lines on a television screen would fluctuate causing " streaking." Transistors may be used instead of diodes in the clamp circuit.

Abstract: 1459349 Cine sound camera AGFAGEVAERT AG 12 July 1974 [14 July 1973] 30987/74 Heading G2E  In a cine camera with sound-recording means, the sensitivity of the recording means is variable in accordance with the focal length setting of a zoom lens of the camera. As shown, the microphone circuit is connected via terminals 17, 18, 19 to corresponding terminals 20, 21, 22 on the camera 1. The signal passes through a variable resistor 5 connected to the input of an amplifier 6 to magnetic sound-recording head 8, 9, where recording on to a film strip 23 takes place. The zoom lens has a movable element 2 which is mechanically linked to the tapping 4 on resistor 5. Thus as the focal length setting of the lens increases, resistor 5 is altered so that the input voltage of amplifier 6, and hence the voltage on the recording head 8, 9, is correspondingly increased. The sound hence appears to be coming from nearer the camera.

Hence the trailer vehicle may be reversed without the brake being automatically applied (by the linkage, not shown, attached to lever 42). The invention includes a pad such as 18 including a backing plate having semicircular "radial" ends and the axial extension 50. The pad 18 is normally urged into contact with abutment surface 26 by a wire spring 60, Fig. 4, having one end connected to one of the two columns (40), on which caliper 38 slides parallel to the disc axis, and the other end connected to a screw 62. The modified brake of Fig. 6, in association with the linkage, including a parking-brake lever 176, of Figs. 8, 9, still prevents brake operation on reversing, but also permits braked parking, whichever direction the trailer tends to move in. Fig. 8 shows the position for overrun braking, with spring 194 compressed and shoulder 196 on tow bar 186, 190 forced by inertia into contact with the end of trailer portion 174; lever 142, Fig. 6, has been pulled into the middle (broken line) position by cable 164 (pad 18 in full-line position). For parking when the towing vehicle and trailer are stationary, lever 176 is pulled to the Fig. 9 position, lever 142, Fig. 6, thus reaching the extreme position (chain lines); pad 18 may be in dottedline position (trailer tending to run backwards). 184, Figs. 8, 9, is a cup member through which cable 164 passes freely.
